Available in PDF, EPUB and Kindle. Book excerpt: The fast consumption of fossil fuel resources and economic competitiveness makes it necessary to increase the efficiency of turbine engines. For this purpose, thermal barrier coating (TBC) has been used on some critical parts of gas turbines. Yttria-stabilized zirconia (YSZ) is widely and commercially used as a ceramic top coat material for TBC in the gas turbine system. On the other hand, the efforts to identify new material having better properties than YSZ have been continued. Gadolinium zirconate (GZ) is a promising alternative TBC material with its lower thermal conductivity, better sintering ability, and higher melting point and phase stability than YSZ. However, recent research studies on the responses of GZ-based TBC materials to the complex demands of modern gas turbine applications should be gathered under a study by comparing them with the results of traditional TBC material. This chapter discusses the GZ based TBC system, specifically addressing issues related to the production process and designing of the coating architecture, in comparison with some of the significant properties with YSZ and the test methodology. Moreover, the chapter also contains information about laser surface modification of the GZ-based TBC.
Book Synopsis Gadolinium Zirconate as a New Material for Thermal Barrier Coatings by : Li Wang
Download or read book Gadolinium Zirconate as a New Material for Thermal Barrier Coatings written by Li Wang and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal barrier coatings (TBCs) have been widely used to protect the superalloy components from the hot gas stream in gas turbine engines. Driven by the higher inlet temperature of modern gas turbine engines for higher efficiency and less harmful gas emission, exploration of TBC new materials and thermal radiation effects of TBCs have recently attracted more attentions. This research explored the potential application of gadolinium zirconate as a promising new TBC material due to its lower thermal conductivity, higher phase stability, and higher CMAS-resistance than conventional YSZ material. The thermal cycling tests were performed using a novel test rig which was designed to mimic the complex working condition of TBCs, and the thermal radiation properties were characterized in the wavelength range where turbine engine thermal radiation is most concentrated. This book is suitable for both beginners and professions in the field of TBCs, as it covers both the brief introduction of TBC system, deposition methods, recent development and the in-depth analysis of failure mechanisms and different models to determine the coating absorption and scattering coefficients.

Book Synopsis Environmental Barrier Coatings by : Kang N. Lee
Download or read book Environmental Barrier Coatings written by Kang N. Lee and published by MDPI. This book was released on 2020-12-29 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global increase in air travel will require commercial vehicles to be more efficient than ever before. Advanced engine hot section materials are a key technology required to keep fuel consumption and emission to a minimum in next-generation gas turbines. Ceramic matrix composites (CMCs) are the most promising material to revolutionize gas turbine hot section materials technology because of their excellent high‐temperature properties. Rapid surface recession due to volatilization by water vapor is the Achilles heel of CMCs. Environmental barrier coatings (EBCs) is an enabling technology for CMCs, since it protects CMCs from water vapor. The first CMC component entered into service in 2016 in a commercial engine, and more CMC components are scheduled to follow within the next few years. One of the most difficult challenges to CMC components is EBC durability, because failure of EBC leads to a rapid reduction in CMC component life. Key contributors to EBC failure include recession, oxidation, degradation by calcium‐aluminum‐magnesium silicates (CMAS) deposits, thermal and thermo‐mechanical strains, particle erosion, and foreign object damage (FOD). Novel EBC chemistries, creative EBC designs, and robust processes are required to meet EBC durability challenges. Engine-relevant testing, characterization, and lifing methods need to be developed to improve EBC reliability. The aim of this Special Issue is to present recent advances in EBC technology to address these issues. In particular, topics of interest include but are not limited to the following: • Novel EBC chemistries and designs; • Processing including plasma spray, suspension plasma spray, solution precursor plasma spray, slurry process, PS-PVD, EB-PVD, and CVD; • Testing, characterization, and modeling; • Lifing.

Book Synopsis Properties and Characterization of Modern Materials by : Andreas Öchsner
Download or read book Properties and Characterization of Modern Materials written by Andreas Öchsner and published by Springer. This book was released on 2016-07-30 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on robust characterization and prediction methods for materials in technical applications as well as the materials’ safety features during operation. In particular, it presents methods for reliably predicting material properties, an aspect that is becoming increasingly important as engineering materials are pushed closer and closer to their limits to boost the performance of machines and structures. To increase their engineering value, components are now designed under the consideration of their multiphysical properties and functions, which requires much more intensive investigation and characterization of these materials. The materials covered in this monograph range from metal-based groups such as lightweight alloys, to advanced high-strength steels and modern titanium alloys. Furthermore, a wide range of polymers and composite materials (e.g. with micro- and nanoparticles or fibres) is covered. The book explores methods for property prediction from classical mechanical characterization-related fields of application, for example, from wear, creep, fatigue and crack growth, to specific surface properties, to dielectric and electrochemical values. As in all fields of modern engineering, the process is often accompanied by numerical simulation and optimization.

Available in PDF, EPUB and Kindle. Book excerpt: This work formed the second part of an investigation into the use of Gd203 as an alternative stabilizer for Zr02-based thermal barrier coating (TBC) materials. The current state-of-the-art TBC material, Y203-stablized Zr02 (3.5-4 mole percent y203), referred to as YSZ, suffers from limited durability at use temperature above 100-1200 deg C. Our previous work investigated the influence of Gd203 concentration on the sintering and phase stability of conventional Zr02 powders. In this work, the effect of Gd203 concentration (420mo1%) on the sintering and phase transformation of plasma-sprayed Zr02 powders was investigated and the data were compared with those for YSZ.
